PNAS: Historical collections reveal patterns of diffusion of sweet potato in Oceania obscured by modern plant movements and recombination.
In the first origin, the Polynesian sweet potato (Kumara lineage) was
introduced by Polynesian voyagers who collected it somewhere from the
western coast of South America, between 1000 and 1100 A.D.
Just click through and go look at "Figure 1", which shows the spread of the sweet potato across the Pacific Ocean, tracked partially by the evolution of local names.
